Teleradiology: The Evolution of Telemedicine in Radiology. The idea of communicating via wire transmission was first introduced by the telephone almost one and a half-century ago. Since that time, the same technique has been applied and has been instrumental in telemedicine’s evolution, which is the practice of using doctors that are not in the same place as the patient.
According to a nationally representative survey, Telemedicine Technology is used by Radiology for patient interactions more than any other medical specialty. Radiologists need to balance their time between seeing patients and consulting with other medical professionals and Telemedicine software and tools made that possible.
By doing telemedicine practices, radiologists can do much work through HD video and high-quality audio. For the busy radiologist in the digital age, telemedicine is more than just a fad. A number of patients & professionals are jumping on the bandwagon and reaping the benefits of real-time consults with telemedicine tools.
Teleradiology uses images from diagnostic departments, without needing the patient’s presence. However, it can’t replace hands-on clinical evaluation, risking lower care quality and higher costs due to potential errors from missing vital patient information gathered during traditional exams

ToggleHistory of Teleradiology
The history of teleradiology is almost half a century long. It has played a significant role in the formation of the entire telemedicine sector. The idea of using wire transmission to communicate was first introduced for the telephone nearly 150 years ago. The same technique has been used and is instrumental in Telemedicine’s evolution. This is the practice where doctors are located far away from the patient. The Queen Mary, an ocean liner, used the ship’s marine radiotelephone for medical consultations in the 1930s. An onboard doctor would consult with external sources and then act as a consultant to individuals aboard other ships in need of medical attention
In the 1960s and 1970s, there was a lot of experimentation and research to improve broadcast television and closed-circuit transmissions of medical images captured by X-rays. The images were generally related to radiology, dermatology, and pathology. A breakthrough was made when Dr. Kenneth Bird, Boston’s Massachusetts General Hospital, was able to install an interactive television system that connected Logan Airport to the hospital. This could be used to provide medical care for travelers.
Walter Redd General Hospital in Washington D.C. had a similar situation. A closed-circuit television was used to establish a link between radiology and emergency rooms. The transmission process in the early days was slow. You could only share one image at once and the contrast and resolution were low, making it more of an exhibit than a practical tool for hospitals. Teleradiology was rejected by most healthcare centers in the early days of telehealth because it required high maintenance and operating costs.
Teleradiology in the 1980s was primarily printed copies sent to the radiologist. He would then record a report onto a cassette tape. The tape would be sent to the original facility, where it would be transcribed into a paper report. The turnaround time for these studies would be days, sometimes even weeks. This would be fine for routine studies, but not in emergency situations.
While some modalities (MRIs, CTs, X-ray machines) produce films or digital images that can be scanned into a new digital image, it was difficult to display the digital copies on other machines. In 1983, the American College of Radiology and the National Electrical Manufacturers Association created an open standard that allows medical images to digitally store. Although the ACR/NEMA 300 standard had its limitations, it was not adopted by all manufacturers.
